SPECIFICATION forming part of Iletters Patent No. 732,456, dated J ne 30, 1903. Application filed September 16,1901. Renewed llllarch 12, 1903. serial No. 147,530. on, model.)

To a whom, it may concern:

Be it known that I, BENJAMIN F. STARK, of Homestead Allegheny county, Pennsylvania, have invented a new and useful Window, of

5 which the following is a iull,clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which' Figure 1 is an inner front elevation of my improved window; and Figs. 2 and 3 are vertical cross-sections of the same, showing-the parts in closed and open positions, respectively. v

Myinvention relates to the class of windows which are provided with movable sashes or portions to act as ventilators, and is especially designed for use in car-windows, though it may be employed in other locations. ts

object is to provide a window of this charac- 2o ter which can be cheaply and easily made and installed and which will allow of good ventilation while largely preventing the entrance of cinders or impurities.

In the drawings, 2 and 3 represent the top 2 5 and bottom sashes, and 4 and 5 the side rails, of my improved window, which is shown as of the proper size for a car-window. Within the sash are provided two swinging panels 6 7, which are separated by a transverse divid- 3o ing strip or strips 8. Each window is pivoted upon horizontal pins at its lower end and is of ordinary form comprising a frame with a glass panel. The dividing-strip 8 is formed in two parts or is cut away to receive a springroller 9, positioned as shown in Figs. 2 and 3 and having wound thereon a wire screen 10, the outer end of which is secured to the upper sash 11 of the panel 7. 1

In order to close the triangular end openings formed at the ends of each panelwhen they are drawn open, I provide a set of fan-shaped shutters 12. These shutters, which are formed of thin flat strips, are pivoted about a common axis at their lower ends, which is pref- 5 erably the axis of the panel, and each strip is slotted at its upper end, as shown at 13, to

receive a headed pin or rivet upon the next slat, the slats thus being limited and guided in their movements.

On the lower or spring-roller panel I provide swinging dogs 14, which are pivoted to the end rails at 15 and are provided with shoes 16, of rubber or similar material. When this lower sash is opened, the dogs are swung forward, so that their shoes contact with the end rails of the window, thus holding the window open against the closing action of the spring-roller and acting as braces.

The upper panel 6 is similar to the lower, except that instead of using a spring-roller with the wire-gauze curtain wound thereon I employ a narrow wire panel 1'7, having, preferably, a sheet-metal frame and hung upon open hooks 18, secured to the top rail of the window. When the upper panel is 5 drawn open, this wire panel lies across the top of the opening, as shown in Fig. 3, and when the panel is in closed position it drops vertically into the position shown in Fig. 2.

1 The advantages of myinvention result from the simplicity and full number of parts. The window is easily operated, is self-closing Where the spring-roller is used, and is not liable to get out of order. The entering air is directed upwardly, so that there is no direct 7 5 draft into the car or room, and the cinders or impurities drop on the outside of the panels, while the air rises through the screens.

The spring-roller may be mounted upon the top rail of the panel instead of in the window-frame proper, and many other changes may be made in the form and arrangement of the parts without departing from my invention.

- I claim- '85 a 1. In a ventilating-window, a panel pivoted at its lower end, its upper end being arranged to swing inwardly, a single top closure of reticulated material arranged to close the top of secured to the top of the panel, and arranged to cover the opening in the dill erent horizontal positions, and movable end closures arranged to compel the air to pass upwardly through the reticulated material into the room; substantially as described.

In aventilating-window, a panel pivoted at its lower end, the upper end being arranged to swing inwardly, a spring-roller having reticulated material Wound thereon with one end secured to the top of the panel, and arranged to cover the opening in the dilferent horizontal positions, and movable end closures arranged to compel the air to pass upwardly through the reticulated material into the room, the spring-roller being mounted in the
